bug#60543: 29.0.60; c-ts-mode: Labels are not properly indented

[Mohammed Sadiq]

With the default "gnu" style, labels are not properly indented.

Eg., for the following code:

int
main (void)
{
end:
  clean ();
}


I expect to get the following indentation for "end:" (single space
before "end" for "gnu" style, and no indentation for "linux" style):

int
main (void)
{
 end:
  clean ();
}
